Is Yuji a geisha?

No, according to Records of the Historian and History as a Mirror, Xiang Liang killed people to avoid disaster and brought Xiang Yu to Wuzhong, which is Suzhou today. The Yu family is a prominent family in Wuzhong (at the end of Qin Dynasty, wuyue was set as Huiji County, and Wu (now Suzhou) was taken as the county government). Xiang Liang's uncle made friends with the children in Jiangdong here. Yu Ji (estimated to be a local aristocrat), a beautiful woman of the Yu family in Wuzhong, admired Xiang Yu's reputation, married Xiang Yu and stayed with her all the time. Or it can be said that Xiang Yu was lucky enough to know Yu Ji, and he got this beauty. Yu Ji often goes out with Xiang Yu. In the late period of the Chu-Han dispute, Xiang Yu tended to lose. In 202 BC, it was besieged by the Han army (now south of Lingbi County, Anhui Province), and the food was serenaded. Embattled at night, heartbroken. Facing Yu Ji, he drank wine and sighed in the camp: "If you pull out the mountain, you will be angry and you will not die." The lyrics are desolate and tragic, with tender feelings, which is called "Children's Song" in history.
